The innovative TI-58 was the perfect base for a lot of customized calculators. This one was used end of the 70^th by insurance agents of the German LVM company. The idea behind these products was the novelty of the Solid State Software Modules™ with up to 5000 program steps.

This software was written by the SW-engineers of the LVM company and programmed into the modules by Texas Instruments.

Compare it with a similar product by the insurance competition Agrippina, Allianz, Lloyd, Nordstern and Victoria or the CAL-Q-TAX calculator. Even the French carmaker Chrysler-Simca used the TI-58, don't miss the Chrysler Credicavia.

We know five different approaches of the module expansion:

• Standard modules like the Master Library use only the small sticker
   above the A,B,C,D, and E keys.
• Other modules like this LVM Insurance calculator make use of a colorful keyboard mask.
• Customized calculators like the USMC AV-8C calculator or insurance calculators
   sold by Allianz and others use special keyboard arrangements.
• The CAL-Q-TAX calculator uses an extender instead the usual drop-in modules.
• The Kodak Q-700 Program Adapter makes use of a snap-on cover with
   an individualized printing.

Dismantling the LVM Insurance calculator reveals a standard TI-58 calculator manufactured in October 1980.

The calculator was available till the year 1983.
